Codex Atlanticus 1478-1518

The Codex Atlanticus is the largest collection of Leonardo’s
papers ever assembled, which was originally put together by the
sculptor Pompeo Leoni. It takes its name from its large size, being
comparable to an atlas.

The Codex Atlanticus reflects
every aspect of Leonardo’s interests, including mechanical science,
mathematics, astronomy, geography, botany chemistry and anatomy. The
drawings represent a broad time-span and are varied in type. Studies
relating to painting, sculptural, architectural and engineering
projects are also included, such as the Adoration of the Magi altarpiece, the Sforza equestrian monument, and the dome of Milan Cathedral.

The manuscript is now arranged in 12 volumes, comprising of over 1100 miscellaneous drawings and fragments by Leonardo.
